Patent DE-4326912-A1 (DE)
Title: Pressure filter, esp. for use in extrusion of synthetic fibres - in which flow distribution plate between filter stack and extrusion nozzle plate is either fixed to, or can move axially on, extension of filter pressure piston
Inventor: RUST JUERGEN
IPC: B01D25/00
Filed: 1993-08-11
Abstract: A pressure filter (1) consists of a housing (2) containing a filter stack (3) which is compressed by a piston in relation to the pressure of the fluid being filtered. The filtrate leaves the filter via a nozzle plate (7). The proposed innovation is that a movable distribution plate (18) is provided between the filter stack and the nozzle plate and that piston and distribution plate both move in relation to the applied fluid pressure. Pref. the filter stack has an annular cross-section and is located between the piston and an annular flange (12) on the filter housing. The piston is provided with a rod (4) which extends through the filter stack and to which the distribution plate is fixed, so that a force is applied to the piston in the direction to the annular flange. The piston and the stack are surrounded by an annular fluid inlet channel (16), and the fluid passage (19,20) is further defined by the piston rod and the filter stack, and by the distribution plate and the annular flange and nozzle plate. USE/ADVANTAGE - Esp. for filtration of synthetic fibre materials immediately before extrusion. An even distribution of the fluid over the nozzle plate is provided under all pressure and flow conditions.

Title: Semiconductor memory device
Inventor: OOISHI TSUKASA
IPC: G11C11/4091
Filed: 1994-02-24
Abstract: A sense amplifier (SA1) with a pair of NMOS transistors (4, 5), which are connected in series between a pair of bit lines (BL, /BL), differentially amplifies the potential difference between the pair of bit lines (BL, /BL) by reducing the source potentials of the NMOS transistors (4, 5) to earth potential (GND). A NMOS transistor (17) is activated for a predetermined time after the initiation of a differential amplification by the sense amplifier (SA1), as a result of which the source potentials of the NMOS transistors (4, 5) are controlled during this predetermined time to achieve a potential (V1) which is lower than the earth potential (GND). As a result, the operating latitude of the NMOS transistors (4, 5) is increased during the predetermined period of time. <IMAGE>

Title: Method for applying gas at two sequential pressures to microporous membrane filter
Inventor: SAIER HANS-DIETER DR
IPC: B01D65/02
Filed: 1994-06-21
Abstract: A process to clean esp. a microporous membrane filter (14) uses an assembly (10) to filter a liquid containing a substance such as a suspension or emulsion. The novelty is that the process incorporates the following steps: (a) The unfiltered liquid inlet (20) and outlet (30) valves are closed and gas introduced at determined pressure (P1) to filter chamber (18); filtrate is displaced from the filtrate chamber (18) through the membrane filter (14) into a chamber containing unfiltered liquid (16); the concentration is not controlled; gas bubbles do not reach the chamber containing unfiltered liquid (16) through the membrane (14). (b) The concentrate outlet valve (30) is closed and the gas pressure is raised from the initial value (P1) to a higher value (P2) for a predetermined time (T); the gas in the liquid close to the membrane (14) loosens deposits on the membrane (14) but without gas bubbles escaping into the liquid within the chamber (16). (c) The gas pressure in the chamber (16) is quickly relaxed.
